Mag One Swivel Earpiece with In-Line Microphone & PTT

The Motorola HKLN4424 Mag One Swivel Earpiece with In-Line Microphone and Push-to-Talk (PTT) provides a lightweight and discreet audio solution for compatible Motorola portable two-way radios.

Featuring a comfortable swivel C-style earpiece, the HKLN4424 fits securely around the ear while delivering incoming radio communications directly to the user. The adjustable swivel design allows the earpiece to be positioned for a comfortable fit and can be worn on either the left or right ear.

The accessory features an in-line microphone and Push-to-Talk (PTT) button, allowing users to transmit messages without repeatedly reaching for or removing the radio. The compact in-line control keeps the microphone and PTT conveniently accessible during everyday operation.

A single-wire design combines the receive audio, microphone, and PTT functions into one streamlined cable, helping reduce cable clutter compared with multi-wire surveillance accessories.

The HKLN4424 connects directly to compatible Motorola portable radios using a dual-pin accessory connector, eliminating the need for a separate audio adapter on directly compatible radios.

Its lightweight design makes the HKLN4424 comfortable for extended wear and provides a practical alternative to larger headsets and remote speaker microphones. Incoming communications are directed to the user's ear rather than through the radio's external speaker, providing greater privacy and discretion.

The HKLN4424 is ideal for retail, hospitality, security, education, property management, restaurants, maintenance, warehousing, event operations, and other professional environments where lightweight and convenient radio communications are important.

Important

The HKLN4424 is a single-wire transmit-and-receive audio accessory.

Incoming communications are heard through the swivel earpiece, while outgoing communications use the accessory's in-line microphone and Push-to-Talk button.

The earpiece uses a swivel C-style design and can be positioned for use on either ear.

The HKLN4424 connects directly to compatible Motorola radios through a dual-pin accessory connector.

This accessory should not be confused with Motorola earpieces that use clear acoustic tubes or separate microphone/PTT wires.
